4.5 Connection of controller PC-3100 and transmitter PH-300T:
A. Connect the GLASS point of transmitter PH-300 terminal to the electrode central spindle.
(Note: Remove the black conductive rubber); connect the REF point of transmitter PH-300
terminal to the electrode network cable.
B. See the two-wire distributing system and three-wire distributing system in the following
page.
C. PT-1000 on transmitter PH-300 terminal is an automatic temperature compensation probe,
or applies a fixed temperature compensation resistance.
D. The V+ and V- of transmitter PH-300 terminal respectively connect to DC12V+ and – of
the controller.
E. The S+ and S- on transmitter PH-300 terminal respectively connect to GLASS and REF of
the controller.
F. The I+ and I- on transmitter PH-300 terminal are output (4-20mA), which can connect to
devices that receive current signals. (Note: The current output signal of this transmitter
is not insulating, so use it with much care!)
Note: Refer to the following table for proper fixed temperature compensation resistance
